As depicted in figs. 1 and 2, seat belt device for vehicle 10 includes driving attitude to keep the component 20 drive member 40 towards vehicle rear-side.It addition, as in figure 2 it is shown, seat belt device for vehicle 10 includes that retainer 41, retainer 41 make attitude keep component 20 to be maintained at following position: under seat harness contraction state, attitude keeps component 20 to extend obliquely from bottom forward upward.Figures 1 and 2 show that drive member 40 is by being connected across the situation that the spring 40A that car body side fixes between component 42 and bracket 25 is formed.But, drive member 40 be possible with from constrictor pull ribbon pulling force the component towards vehicle rear-side and without arranging spring.Above-mentioned structure is common to all embodiments of the present invention.
The first embodiment of the present invention farther includes following structure.In the first embodiment of the present invention, during waist side anchor locking member 12 is attached to a pair upper rail 55 of front stall 50 one so that the most pivotable.Reference 58 represents the bolt being fixed on upper rail 55.Waist side anchor locking member 12 is pivotable around bolt 58.Bolt 58 constitutes the pivotal line (owing to pivotal line is bolt, therefore pivotal line is represented) of waist side anchor locking member 12 by reference 58.
As shown in Fig. 1 and Figure 14, in front stall 50, in order to allow the lengthwise position scalable of front stall 50, upper rail 55 is relative to the lower guideway 56 being fixed on vehicle the most slidably.It addition, in order to the upright position scalable allowing front stall 50, cushioning frame 54 and medicated cushion 53 vertically can be shifted relative to upper rail 55 by elevating lever.Elevating lever is included in plane in the vehicle longitudinal direction the link rod 57 pivoted, therefore the lift adjustment of front stall 50 along with cushioning frame 54 and medicated cushion 53 relative to the vertical shift of upper rail 55.
In order to suppress the position holding mechanism 20 upward displacement relative to cushioning frame 54, it is desirable to bracket 25 is attached to cushioning frame 54.But, when waist side anchor locking member 12 is attached to one in upper rail 55, owing to cushioning frame 54 vertically and longitudinally shifts relative to upper rail 55 when the lift adjustment of seat 50, therefore the pivot axis attitude of bracket 25 keeps component 20 and the centrage F (Fig. 9) of ribbon 11, wherein ribbon 11 extends obliquely from pivot 58 forward upward of waist side anchor locking member 12 under seat harness contraction state B1, and irrational load is applied to attitude along the direction being perpendicular to centrage F and keeps on component 20 and ribbon 11 so that ribbon 11 deforms.
In order to prevent irrational load, when waist side anchor locking member 12 is pivotably coupled to one in upper rail 55, bracket 25 is supported by seat protection cover-cap 61 can to shift in the vehicle longitudinal direction, as shown in Figures 9 to 11.Thus, when cushioning frame 54 and medicated cushion 53 are raised, bracket 25 is absorbed relative to the length travel of seat protection cover-cap 61 by bracket 25 relative to the length travel of upper rail 55, and bracket 25 is kept the slip of component 20 to absorb by ribbon 11 relative to attitude relative to the vertical displacement of upper rail 55.As a result, attitude keeps the centrage F pivot 58 through waist side anchor locking member 12 of component 20 and ribbon 11, and inhibits attitude to keep the load along the direction being perpendicular to centrage F on component 20 and ribbon 11.
Fig. 9 to Figure 11 shows that bracket 25 is supported so that the most displaceable structure by seat protection cover-cap 61.Seat protection cover-cap 61 is inserted from above in the notch of seat protective cover 60 and is connected to seat protective cover 60.Seat protective cover 60 and seat protection cover-cap 61 are all formed from a resin.
Seat protection cover-cap 61 has a pair upper and lower cover slide rail 62 extended in the vehicle longitudinal direction.The head 63a of the stud pin 63 being fixed on bracket 25 inserts between the pair of slide rail 62.The head 63a of stud pin 63 is along slide rail 62 the most slidably.
As shown in Figure 10, retainer 41 is arranged on the rear end of slide rail 62.When the head 63a side backward of stud pin 63 shifts with contact retainer 41, bracket 25 can not shift further towards vehicle rear-side.Thus, retainer 41 (Figure 10) is used as to make attitude keep component 20 to be maintained at the retainer 41 (Fig. 2) of following location: under seat harness contraction state, attitude keeps component 20 to extend obliquely from bottom forward upward.As shown in figure 11, loosen suppression rib 64 to be formed between the pair of slide rail 62 of seat protection cover-cap 61 thus the head 63a of orientation column bolt pin 63 highlights.Loosen suppression rib 64 suppressed column bolt pin 63 in the lateral direction of the vehicle loosen.
